Domain and Subdomain wordpress

Mat ‎ There is some learning there!

Mat ‎ Do you have any video or document tutorials? I find it a bit difficult to understand because there are too many techniques.

Dương Nguyễn it will be difficult to execute such a case scenario if you dont have much experiance. Also you should validate your idea again before even implementing (PoC).

I dont have any out of the box solution for you or a learning path but you can use ChatGPT to guide you.

Before you begin you should already ask yourself some fundamental questions:

• what server do you need to handle such a case
• what external ESP will allow you to have a such a setup for 1000s of subdomains and how will you manage so many sending domains (From: subdomain) and keep them warmed up (to avoid spam).
• How are you going to send email high volume (marketing and transactional emails) from subdomains and not being banned
• How are you going to automate the setup process for this case scenario especially if you dont have much experience with it. Doing it manually will take you "some" time.

Maybe it would be more beneficial for you to understand this setup by just setting up 1x end-to-end case (1x subdomain) instead of thinking of doing it for 1000s subdomains.

Also probably it would be easier if you would collect your data from all fluent forms (from subdomains) to one FluentCRM (primary domain) and send emails only from that primary domain (one sender domain) not from each subdomain but again I am not sure what is your business case and it is above what I can help here.

Maybe someone else can offer you a ready $olution.

How to send emails from different SMTP profile based on Tags (where tag determine from which subdomain we should send out email)?

You're working with FluentCRM and want to send campaigns where the sending SMTP changes based on user tags, and those tags correspond to specific subdomains.

Scenario Overview

Imagine these tags:

• subdomain_finance → sends emails from [email protected]
• subdomain_events → sends emails from [email protected]
• subdomain_support → sends emails from [email protected]

Each of these senders is connected to a different SMTP configuration via FluentSMTP.

What You Need

Before building the logic:

• FluentCRM installed
• FluentSMTP with multiple configured connections
• Verified sending emails (finance@..., events@..., etc.)
• PHP dev access or a plugin for FluentCRM automation hooks (like Code Snippets)

Step-by-Step Flow

1. Tag Contacts
   • Tag: subdomain_finance
   • Tag: subdomain_events
   • Tag: subdomain_support
2. Configure Multiple SMTP Connections
   • Add a separate SMTP connection for each sender
   • Use sender-specific settings and emails
3. Inject Custom SMTP Routing Based on Tags
   • Use this PHP snippet in Code Snippets or your custom plugin:

add_filter('fluentcrm_email_sending_options', function ($emailOptions, $subscriber) {
    $tags = $subscriber->tags;

    if (in_array('subdomain_finance', $tags)) {
        $emailOptions['from_email'] = '[email protected]';
        $emailOptions['from_name'] = 'Finance Team';
        $emailOptions['connection'] = 'finance_smtp';
    }

    if (in_array('subdomain_events', $tags)) {
        $emailOptions['from_email'] = '[email protected]';
        $emailOptions['from_name'] = 'Events Team';
        $emailOptions['connection'] = 'events_smtp';
    }

    if (in_array('subdomain_support', $tags)) {
        $emailOptions['from_email'] = '[email protected]';
        $emailOptions['from_name'] = 'Support Team';
        $emailOptions['connection'] = 'support_smtp';
    }

    return $emailOptions;
}, 10, 2);

Last step

Create Campaign Normally

• Go to FluentCRM > Campaigns
• Select your audience (all tagged contacts)
• Create and schedule the campaign

The hook will auto-route each email to the correct sender and SMTP.
